Glasgow, Scotland Application February 25, 1939, Serial No. 258,404 In Great Britain February 9, 1939 2 Claims.

This invention relates to hair curlers of the type including a drum Whereon is to be Wound the wisp of hair to be curled, a spring-urged clamp mounted upon the drum and engageable 5 with that portion of the Wisp Which, in the finished curl, forms the innermost convolution, and a linger grip rotatably mounted on the drum and serving as a carrier for a hair pin .adapted to be applied to the iinished curl on release of the clamp and on Withdrawal of the drum from the interior of the curl.

In the operation of a hair curler constructed as described, the free end ofv the wisp of hair is clamped to the drum. Thereupon a hair pin is inserted into the finger grip and the linger grip is held by the fingers of one hand, treated for convenience of description as the left-hand. The ngers of the right-hand are now applied to the end of the drum remote from the nger grip 2O and the drum is rotated by the fingers of the right-hand and supported by the ngers of the left-hand through the intermediary of the linger grip. Resistance to rotation of the drum is offered by the hair curl Which naturally tends to 25 straighten so that, in the rotation of the drum by the fingers in one direction, it tends to rotate in the opposite direction as soon as the fingers employed to rotate the drum ar'e released, it being understood that no resistance to rotation is offered by the fingers of the left-hand which support the drum through the intermediary of the freely rotatable nger grip.

The present invention has for its object Ato provide means operating through the intermediary of the fingers which engage the linger grip adapted to prevent retrograde rotation of the drum. y

With this object in view, the invention consists in the incorporation in a hair curler of the 40 type described of a linger grip which is vso mounted upon the drum as to confine the drum to uni-directional rotation so long as the finger grip is held against rotation.

According to a preferred embodiment of the invention, the drum is provided at the end which is adjacent `to the finger grip with a circular roW of ratchet teeth and the finger grip incorporates a spring-urged detent engageable with the ratchet teeth and limiting to one direction the rotational movement of the drum relatively to the finger grip.

As preferably arranged, the finger grip is in the form of a ferrule sleeving one end of the .drum and provided with a detent tooth and the drum is formed with a circumferential groove accommodating the tooth and presenting a circular .row of ratchet teeth engageable With said tooth, engagement of the detent tooth With the ratchet teeth serving to prevent retrograde rotational movement of the drum relatively to the ferrule 5 and engagement of the detent tooth With the Walls of the groove serving to prevent axial displacement of the ferrule relatively to the drum.

Desirably, the ferrule is composed of resilient metal and the detent tooth is struck from the 10 body of the ferrule.

A hair curler constructed in accordance With the invention is illustrated in the accompanying drawing in which Fig. 1 is an elevation, Fig. 2 a longitudinal section, and Fig. 3 a section drawn to a larger scale on the line SH3 of Fig. I2.

The hair curler shown includes a drum I whereon is to be wound the Wisp of hair to be curled. Mountedupon the drum I is clamp 2 urged by a spring 4 into engagement With that portion of the vvisp ofhair (not shown) Which, in the iinished curl, forms the innermost convolution. A ling-er grip 5 rotatably mounted on the drum I serves as a carrier for a hair pin 6 adapted. to be applied to the finished curl on release of the clamp 2 and on Withdrawal of the drum from the interior of the curl.

The drum I is provided at the end which is adjacent to the finger grip 5 with a circular row of ratchet teeth 'I and the linger grip incorporates a spring-urged detent tooth' engageable with the ratchet teeth I and limiting to one direction the rotational movement of the drum I relatively to the finger grip 5 so long as the finger grip is held against rotation.

The iinger grip is shown as in the form of a metallic ferrule sleeving one end of the drum I and the detent tooth 8 is struck from the body of the ferrule and the drum is formed with a circumferential groove 9 accommodating the tooth 8 and affording the circular row of ratchet teeth 1.

It will be seen that engagement of the detent tooth 8 with the ratchet teeth 'I serves t0 prevent retrograde rotational movement of the drum I relatively to the ferrule and that engagement of the detent tooth 8 With the lateral Walls of the groove 9 serves to prevent axial displacement of the ferrule relatively to the drum I.

I claim:

1. A hair curler comprising, in combination, a drum provided with hair-clamping means and adapted to be rotated by the lingers of one hand, a iinger grip rotatably mounted on said drum and adapted to be held by the lingers of the 55 on said drum and adapted. to clamp the hair t0 be curled, a iinger grip formed as a ferrule rotat-t ably mounted on said drum and adapted to be held by the ngers of the other hand, a detent tooth formed on said ferrule and projecting into said groove so as to engage said ratchet teeth so that engagement of said detent tooth with said ratchet teeth prevents retrograde rotational movement of said drum relatively to said nger grip and engagement of said detent tooth with the Walls ofvsaid groove prevents axial displace- 10 ment of said finger grip relatively to said drum.
